Day 36: 3rd Law & Cosmic Voyage

Today is day 2 of the NSTA Regional Conference, so students have a sub again.

AP Physics: Newton’s 3rd Law

Students drew free-body diagrams for various cart collisions and predicted how the force on each cart should compare. It usually drives students nuts that I won’t tell them whether they are right in this activity, so I think it will be less frustrating for them to do this with a sub, even if I’ll miss out on hearing them talk it through. On Monday, we’ll put some force sensors on carts and see if the students were right.

Earth Science: Cosmic Voyage

The curriculum calls for showing The Cosmic Voyage during the astronomy unit, so I took advantage of the easy sub plan.
